OF YORK, N.

IMPROVEMENT iN COTTON-PICKERS.

Specification forming part of Letters Patent No. 29,435, dated July 31, 1860.

To all whom, it may concern.

13c it known that I, LEWIS JENNINGS, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Cotton licker or Harvester; and I do hereby declare that the following is a full, clear, and exact description of be same, reference being had to the annexed drawings, making a part of this specification, in which- Figure'l'is' a side sectional view ofmy invention. Fig. 2 is a detached plan View of a section of the same.

Similar letters of reference indicate corresponding parts in the figures.

To enable those skilled in the art to fully understand and constructmy invention, I will proceed to describe it.

A represents the case of the implement, which may be constructed of shectmetal, of the usual form, and provided with a staple, B, at its back end, through which a strap passes to suspend it to the operator, a bag or cotton-receptacle being attached to the back part of the case. \Vithin the case A, near its back end, a pulley, O, is placed, anda smaller pulley, D, is placed at the front part of the case. The pulley D is provided with radial spurs or teeth a, which project a suitable distance from the periphery of the pulley. Around the pulleys 0 D endless belts are placed side by side, and they pass around the pulley D between the circumferential rows of spurs or teeth a, as shown clearly in Fig. 2.

Fis an elastic plate, which projects over the pulley D, and by yieldiug'fornis a compensating orifice for 'the case, to compensate for any irregularities as regards the passing of the cotton into the case. The axisof the innermost pulley, O, is provided at one end with a crank.

The operation is as follows: The operator slings the implement from his shoulder and turns the crack of pulley O, the pulleys C D and belts E moving in the direction indicated by the arrows. The pulley D, as it rotates, is prc sented to the cotton, and the spurs or teeth a extract the cotton from the bolls and carryit into the case A, the belts E conveying the cot.- ton to the back endof the case, the cotton being discharged over the pulley C and falling into the bag or receptacle, as shown in red.

The belts E perform two functionsto wit, the conveying of the cotton through-the case A and the stripping of the cotton from the spurs or teeth a. It will be seen by referring to Fig. 1 that the passing of thespurs or teeth down between the belts will have the efl'ect to strip the cotton therefrom. The rotation of the spurs or teeth also assists the belts in feed ing or conveying the cotton back through the case.

Having thus described my invention, what I claim as new, and desire to secureby Letters Patent, is

The employment of the spur-wheel D, in combination with belts E, which pass between the spurs a, 'so that as the spurs sink between the belts the cotton will be stripped from-the spurs and left upon the belts. all substantially as herein shown and described;

L. JENNINGS.
